Problems solved by technology

[0006] The flame from the auxiliary burner according to EP-A-2,085,696 consists of multiple flames which makes it more difficult to control the stability of the flame
Also, in the auxiliary burner of EP-A-2,085,696, there is no pre-mixing of fuel and oxygen-containing gas, which increases the risk of ash formation inside the burner
Finally, the manufacture of such an auxiliary burner is relatively complex, since several fuel supply lines should be arranged symmetrically around the centrally-ignited burner

Embodiment Construction

[0035] exist figure 1 , the stabilizer (2) consisting of a conical part (3) and a cylindrical part (4) connected at the upstream end of the conical part (3) is along the longitudinal axis of the burner tube (1) ( 7) Arranged in the center of the burner tube (1). Arrows indicate the direction of flow of the combustible mixture of oxygen-containing gas and fuel gas obtained by mixing fuel gas and oxygen-containing gas in a mixing device arranged in the upstream section of the burner tube. The cylindrical part (4) of the stabilizer comprises a spark plug (5), while an ionizing rod (6) extends from a circular base at the downstream end of the stabilizer (2). The central tube (8) is used to support the stabilizer (2) and to guide the electrical connections to the ionization rod (6).

Abstract

The invention is directed to a burner comprising (a) a burner pipe, (b) mixing means arranged in the burner pipe for mixing an oxygen-containing gas and a fuel gas and for discharging the resulting gas mixture within the burner pipe; and (c) stabilising means downstream of the mixing means in the centre of the burner pipe, wherein the stabilising means comprises a conically shaped body which widens in flow direction.

Description

technical field [0001] The present invention relates to a burner and, more particularly, to a gas burner in which fuel gas and oxygen-containing gas are premixed prior to ignition. The burner according to the invention is especially suitable as an auxiliary burner or heating burner in partial oxidation reactors for the production of synthesis gas by partial oxidation of gaseous hydrocarbon-containing fuels. Background technique [0002] Partial oxidation is used, for example, to produce pressurized synthesis gas, fuel gas or reducing gas. To this end, a gaseous or liquid hydrocarbon fuel and an oxygen-containing gas are introduced into the reactor via a main gasification burner as described, for example, in WO-A-96 / 003345. The flame is maintained in a reactor where the fuel reacts with the oxygen-containing gas to form a gas including carbon monoxide and hydrogen. [0003] In order to start the partial oxidation reactor, the temperature of the reactor and its refractory li...
